Posted by Andrew Gould on 15 January 2022

This video explains how to use DAX time intelligence functions to modify the filter context applied to a measure, allowing you to compare calculations for different time periods. You'll learn the differences between the DateAdd, SamePeriodLastYear, PreviousYear and ParallelPeriod functions. You'll also see how to enter specific dates using the DateValue and Date functions, and how to use these dates in the DatesBetween function. Finally, you'll learn how to calculate moving averages using FirstDate and LastDate functions and the DatesInPeriod function.
